You should use .030" welding wire for thinner materials, typically up to about 1/8 inch, as it provides better control and less chance of burn-through. For thicker materials, .035" wire is preferred because it delivers higher deposition rates and better penetration. Your choice depends on the thickness of the metal you're welding and your specific project needs.
